Plasticizer
Phthalate -based plasticizers are used in situations where good resistance to water and oils is required. Some common phthalate plasticizers are: Low Molecular Weight Ortho Phthalates Dimethyl phthalate (DMP), used in fragrances, as an insect repellent, and in several industrial processes as a solvent/carrier

Phthalates are a group of chemicals used to make plastics more durable. They are often called plasticizers. Some phthalates are used to help dissolve other materials. Phthalates are in hundreds of products, such as vinyl flooring, lubricating oils, and personal-care products (soaps, shampoos, hair sprays).
Phthalates used as plasticizers in rubber and plastic products are
Phthalates used as plasticizers in rubber and plastic products are believed to act as hormone mimics in humans. The value of ΔHcomb for dimethylphthalate (C10H10O4) is –4685 kJ/mol. Assume 0.905 g of dimethylphthalate is combusted in a calorimeter whose heat capacity (Ccalorimeter) is 6.15 kJ/°C at 21.5 °C.

Alternative to Phthalate Plasticizer for PVC/NBR Formulation Used
Phthalates have been extensively used in rubbers formulation as plasticizer additive for PVC and NBR promoting processing parameters or for cost reduction. The most commonly used plasticizer in PVC compounds was di-2-ethylhexyl phthalate (DEHP) currently not recommend due toxicity. DEHP is listed as
- Are all plasticizers phthalates?
- They are mainly used as plasticizers, i.e., substances added to plastics to increase their flexibility, transparency, durability, and longevity. They are used primarily to soften polyvinyl chloride (PVC). While phthalates are commonly used as plasticizers, not all plasticizers are phthalates.
- Why are phthalates used as plasticizers?
- The widespread use of phthalates as plasticizers is due to their ability to significantly improve the flexibility and durability of plastic products. They are effective in lowering the material’s hardness, making plastics easier to process and more comfortable for consumers to handle.
- What is the structure of phthalate plasticizers?
- The structure of phthalate plasticizers is that of a phthalate ester, which is simply a phthalate with, an ester group (see structure below figure 1) (1). (Figure 1.) Phthalate plasticizers are colorless liquids like vegetable oil with a faint odor, and they are insoluble in water.
- Are phthalate esters a good plasticizer?
- Being inexpensive, nontoxic (in an acute sense), colorless, noncorrosive, biodegradable, and with easily tuned physical properties, phthalate esters are nearly ideal plasticizers.
- Are phthalate plasticizers dangerous?
- Phthalate plasticizers have been found to be a health concern when found in direct contact with bodily fluids. Studies performed on laboratory animals have shown that there is direct evidence that certain phthalate plasticizers have a carcinogenic effect in vivo.
- Which phthalate is the dominant plasticizer in house dust?
- HMW phthalates increased from 19% of the ∑plasticizer concentration to 46% between the mid-2000s and the late 2010s in house dust, and from 50% to 63% in SPM samples. Diisononyl phthalate (DINP) replaced DEHP as the dominant plasticizer in both compartments.
